[comp.sys.mips] RISC/os 4.50

jmk@alice.UUCP (Jim McKie) (07/14/90)

Our 6280 came with 4.50, so it's probably time to upgrade
our M/2000 and M/120's. However:

1) trying to make a kernel for an M/120 results in 'is_digi'
   undefined if the c8 driver is not included (referenced in
   kernel.o);
2) is there any documentation on the vfs interface? We have
   our own network filesystem which we'd added in the past to
   the filesystem switch and would like to add it into the
   new system also.

Any help appreciated.

     Add to sysgem.r2400_local:

	EXCLUDE: c8

     VFS is very similar to the construct of the same name in
SunOS 4.0, and thus has a very strong family resemblance to VFS
in SVR4.  MIPS does not document VFS or most other internal kernel
interfaces, since we do not support them (in that we do not promise
to keep them upward compatible across major releases).  On the other
hand, VFS is likely to stay around for a while, with at most relatively
minor changes to the interface.
